` To all whom it may concern:

Be it known that I, JOHN. HUDRY, a citizen of the United States, reslding at Hazle ton, in the county of Luzerne and State of -Pennsylvania, have invented a certain new and useful Improvement in Cribs, of which the following is a full, clear, and exact description.

The object of this invention is to provide ai crib adapted to be folded into co-mparatively small compass, whereby the crib may be placed outef the way when not in use, by rolling it under an ordinary bed, and also adapted lto ybe adjusted vertically so that the mattress of the crib may be brought to a level or in line with the mattress of the ordinary bed when the crib is used alongside of a bed with one of its side guards lowered to permit of the convenient handling of an infant occupying the crib by its mother or other attendant occupying the bed.

The invent-ion consists of a crib comprising a truck or supporting frame having upwardly extending corner posts, a* folding crib structure having corner posts slidably mounted upon the corner posts ofthe truck or supporting frame, means for automat-ieally elevating the crib structure and stopping and locking it in its elevated position at Vany desiredv height; and the invention also consists in providing means for throwing out of operation the mechanism for controlling the 'automatic elevating means, and providing means for manually elevating and lowering the crib structure, all substantially/ as I will proceed now more particularly to set forth and fin lly claim. i ./In the accompanying rawings, illustrat- -""`ing the invention, in the several figures of which like parts are similarly designated, Figure 1 is a perspective view showing the crib in a set-up condition. Fig. 2 is an end view of the manually operating end of the crib, the upper portion being broken away. Fig. 3 is a top plan view. Fig. t is a side elevation, with one of the telescoping corner posts and one ot' the latches for the side rail in section. Fig. 5 is a top plan view of the truck or supporting frame, .showing the controlling means for the automatic operation of the crib and the manual operating means, and Fig.' 6 is a side elevation showing the crib in its folded condition.

The truck or supporting frame comprises the posts 1, connecting cross rails 2, and a central longitudinal bar 3 connect-ing the Patented Feb. 25,1913. V

cross rails 2. The truck isprovided with any suitable rolling'casters 4, preferably of the ball bearing type as herein shown, whereby the crib may be readily rolled from place to place. The posts 1 as herein shown are rectangular in cross section; and be constructed of any suitable light and strong metal, mch as aluminum or brass,

or of any other desired material, and may extend any suitable distance above the cross rails 2 and central bar 3 in accordance with the extent of adjustment it is desired to obtain. The posts are provided with a central longitudinal bore 5, and opposite slots 6 extending into said bore, see particularly Figs.

4 and 5, and recesses 7 in their. upper ends see Fig. 4.

The crib proper comprises the hollow corner posts 8, connecting and slatted end rails 9, and the mattress frame 10 connected to the corner posts 8 by any suitable 4or approved corner fastenings. Above the side rails of the mattress frame 10 and extending between the end posts 8 is a guard rail 11, of sufficient height to maintain the mat- .tress in place upon its supporting frame and may springs. The corner pests 8 are made hollow and correspond in cross-sectional shape to the posts 1 of the truck or supporting frame and are adapted to telescope or' slide upon the posts 1, and fixed in the upper end of the hollow posts 8 are guide rods 12, see Fig. 4, adapted to enter the bores 5 of the posts 1, coiled springs 13 being arranged within the hollow posts 8 upon the rods 12 and engaging the upper ends of posts 8v and resting upon the upper ends of the posts 1, the recesses 7 in the pests 1 affording seats for the lower ends of the springs 13. The rods 12 at their lower ends are provided with cross pins 14, see Fig.4, engaging the slots G in the posts 1, and serving to limit the upward movement of the posts 8. Connected with the posts 8 at their upper ends,

as by rule joints 15, are the extension posts 16 connected at the head and foot of the crib by the slatted rail guards 17, the abutting shoulders of the rule jo-ints 15 being arranged outward so that the posts 16 and their attached guard railsp17 may be folded down. inwardly upon the mattress frame, the

rails 19 in-their position of use any suitable' latches, such 4as sliding-bolt spring latches 20 are secured to the underside of t-he 'upper rails of the side guards 19 and adapted to engage holes or other keepers 21 inthe posts 16, as clearly shown in Fig. 4.

l As more particularly shown in Fig. 3,the mattress frame isv provided with a spring bed bottom 22, constructed of longitudinal transverse strips of thin sheet metal provided at their intersections with comple-l mental slots and lugs for securing the strips together, and supported in said frame by coiledsprings 23, as described andclaimed in an application for vpatent tiled by me May 22, 1912, Serial Number 699,049.

VATitgltecured to and depending lfrom the oppes-ite end rails of the mattress frame 10 l are ratchet bars 24, said bars passing down through openings 25. in the central connecting bar 3 of the truck or supporting trame,-

and mounted to slide upon the central bar 3 and guided in loops 26 on said bar are locking dogs or pawls 27, having their outer ends so constructed as to engage said ratchet bars 24, to lock said bars against upward movement, but permitting a downward movement thereof. Coil springs v28 ary ranged beneath the bar 3 and having one end connected to said bar, as at 2.9', and their other ends connected with pins l3) projecting from the locking dogs 27 through .suit-able slots 31 in said bar 3,-serve normally te keep said locking dogs in engagement with the ratchet bars 24 and permit the downl' ward movement of the ratchet bars in lowering the crib. Connected` to the inner ends 'of the locking dogs 27 are linksv V32, said links at their other ends being connected with a vertical operating rod 33, passing through and guided by a slot 34 in the bar 3, and said rod 33 connected with the ends of'levers 35, having foot pieces 36, and eX- tending outwardly toward the sides of the crib within convenient reach of the operator upon opposite sides of the crib. The

levers 35 are pivotally hung in right angled brackets 37 projecting from and supported by the central bar 3. Mounted to slide upon one of the brackets 37 is a locking plate 38 adapted to engage a hole 39 in the' vertical rod 33 when inits elevated position, to lock the dogs 27 in their retracted position. Also secured to and depending from the oppositeend rails of the mattress frame 10 and passing through slots 40 in the central'bar 3 of the truck or supporting frame 3 are rackbars 41, and supported upon the cross rails 2 of the truck or supporting frame by means of-bearing blocks 42, is a longitudinal shaft 43, having fixed thereon and meshing with the rack bars 41, gears 44, and provided at one end with an operating handle 45. Alsol mounted upon the shaft 43 adjacent to the operating handle 45, is a spur wheel 46, and pivoted upon the cross rail 2 of the truck is a swinging locking plate 47 4adapted to engage saidspur wheel to lock the shaft 43 against rotation.

As shown in Fig. 6, the crib is in folded condition with t-he corner posts 8 of the crib structure depressed or lowered to their fullest extent, and the springs 13 com-- pressed, and when it is desired to set up the crib for use, it is only necessary to' lift the posts 16 with their yconnecting guard rails and raise the side guards 19 until their latches 20 engage the keepers 21 in the posts- 16, and thecrib will then assume the posi.- tion as indicated in Fig. 1. Should it be desired to elevate the crib automatically, the

latch plate'47 is released from the spur wheel 46, and thefoot yplaced upon one or the other of the foot pieces 36 to depress the links 32, thus retracting the locking dogs 27 from the ratchet bars 24 and vpermitting the springs 13 to elevate the crib structure. In order to prevent a too sudden rise of the lever 35,- and through the rod 33 raise the crib structure -under the tension of the springs, the hands of the operator may be I placed upon the upper part of the crib and a slight pressure applied thereto. Upon relea's'ing the pressure of the foot, the locking pawls 27 are again forced into engagement 'with the ratchet bars 24 by the action of 'their springs 23, and the crib structures stepped and locked at any desired elevation.,I

Should it be desiredto lower the crib strucf ture, it isnecessary only to apply pressure to lthe upperart of the crib, the inclined i or beveled sur aces of the locking pawls permitting the downward movement of the crib structure ywithout retracting `the locking pawlsby operating the foot levers, although. this may be 'done it desired. 1n order to.

raise and lower the crib independently oit' the action of the springs 13, the locking pawls 27 are retracted from the ratchet-bars 24-by pressure applied to one er the other of the foot levers, and locking them iii-.their retracted position by forcing the lock-plate 38 into engagement with the hole 39 in the rod 33, thus maintaining the locking pawls in their retracted position. 'Then by rotating the crank handle 45 the crib structure may be elevated and lowered, and locked at any desired elevation, by shitting the' locking plate 47 into engagement with the spur wheel 46. When it is desired to use the crib alongside of an ordinary bed, one of the side guards 19 is lowered, as shown in Fig. Q, by releasing its latches 20, and the crib placed alongside of the'bed, and the crib structure adjusted s'o that its mattress is on a level with the mattress of the bed, thereby making the handling of an infantoccupying the crib more convenient than if the side guard were up or the mattress of the crib were not on a level with the mattress of the bed. When the crib is not in use, and it is desired to get it out of the way, it may be folded and lowered to its fullest extent, as shown in Fig. 6, and shoved or rolled under the' bed.

I do not wish to be limited to the exact details of construction herein shown and described, as the same may be changed in various particulars, and still be within the scope of the invention.
